    Loads On Structures

    This section discusses the principles related to loads on structures, including live load reduction for floors and roofs, tributary areas, and essentials of structural design.

    Learning Practice

  • 6.1

    Live Load Reduction

    Live load reduction principles allow for a decrease in the design live load of structures with large floor areas, reflecting the unlikely simultaneous occurrence of maximum live loads.

    Learning Practice

  • 6.1.1

    Floors

    This section discusses the concept of live load reduction for building floors based on certain conditions outlined by specific codes.

    Learning Practice

  • 6.1.2

    Roofs

    This section discusses the design considerations of various types of roofs, focusing on reduced live loads as per relevant standards.

    Learning Practice

  • 6.2

    Tributary Areas For Beams And Columns

    Tributary areas for beams and columns help determine the vertical loads transferred from slabs to these structural elements.

    Learning Practice

  • 6.2.1

    Approximate Methods

    This section discusses approximate methods for calculating slab loads on beams using tributary areas and uniformly distributed loads.

    Learning Practice

  • 6.3

    Concepts In Structural Design

    This section emphasizes the importance of safety, serviceability, and economy in structural design, along with specific methods like LRFD for ensuring that structures can adequately support applied loads.

    Learning Practice

  • 6.3.1

    Lrfd

    LRFD involves applying load factors to service loads and selecting members with adequate strength to resist these loads.

    Learning Practice

  • 6.3.2

    Load Combinations

    This section covers the concept of Load Combinations in structural engineering, emphasizing the importance of combining different loads safely and economically.

    Learning Practice

  • 6.3.3

    Lrfd Load Combinations

    This section outlines the various Load and Resistance Factor Design (LRFD) load combinations used in structural engineering to ensure safety and reliability.
